Hi I recently worked on an electrical panel which controlled 2 sewage pumps. There is a timer and relay labeled power up timer and power up relay in the panel where the timer energises the relay coil for 12 seconds only immediately after power is switched onto the panel . I'm not sure what the relay is switching for this…

Hi
I recently worked on an electrical panel which controlled 2 sewage pumps. There is a timer and relay labeled power up timer and power up relay in the panel where the timer energises the relay coil for 12 seconds only immediately after power is switched onto the panel . I'm not sure what the relay is switching for this brief period or what the purpose of this is. I couldn't check schematic drawing as it wasn't available. Apologies if the details are vague.
Thanks in advance.
